Updating gm xm radio vin number
GM used a lettered system of automobile platform codes for three decades.These letters were used as the fourth position of the VIN.
This radio code is not required, unless the radio is removed from the vehicle, or the vehicles battery is disconnected.He comes back with the exact same model I have installed.Confused by that, he disappears for another half hour and comes back with the new model number that replaces the original model.Each Year has different break down for each code, a complete list would be a subject of its own.Along with Plants and some model break downs over years.Also mistake on Country codes…GMC light trucks are not listed.
I just bought a 2006 Chevy Colorado for my daughter that had an aftermarket stereo installed, and I wanted to restore the factory radio.
Warning: Issues with the decoding are related to year/model combinations.
Such as the 4.1 V6 is not included in the list, however it was used on El Dorada and some Cadillac models.
Missing Entry: 1991 Limo with engine code 7, is not listed.
Since 1998, many company's in the automotive industry have relied on our radio unlock code service to get their customers up and running!
GM encodes the engine type in character 8 of the VIN.
